Background: Prehospital pediatric endotracheal intubation (ETI) is rarely performed. Previous research has suggested that pediatric prehospital ETI, when performed by ground advanced life support crews, is associated with poor outcomes. In this study, we aim to evaluate the first-attempt success rate, overall success rate and complications of pediatric prehospital ETI performed by critical care transport (CCT) personnel. Methods: We conducted a retrospective observational study in a multi-state CCT service performing rotor wing, ground, and fixed wing missions. We included pediatric patients (<18 years) for whom ETI was performed by CCT personnel (flight nurse or flight paramedic). Our primary outcome of interest was rate of first-attempt ETI. Secondary outcomes were overall rates of successful ETI, complications encountered, and outcomes of patients with unsuccessful intubation. Results: 993 patients were included (63.2% male, median age 12 years, IQR 4–16 years). 807/993 (81.3%) patients were intubated on the first attempt. Lower rates of successful first-attempt intubation were seen in younger ages (42.9% in infants ≤30 days of age). In multivariable logistic regression, lower odds (adjusted odds ratio, 95% confidence interval) of successful first-attempt ETI were associated with ages >30 days to <1 year (0.33, 0.18-0.61) and 2 to <6 years (0.60, 0.39–0.94) compared to patients 12 to <18 years. Patients given an induction agent and neuromuscular blockade (NMB) had a higher odds of first-attempt ETI success (1.53, 1.06–2.15). 13 (1.3%) had immediately recognized esophageal intubation and 33 (3.3%) had vomiting. No episodes of pneumothorax were reported. 962/993 (96.9%) patients were successfully intubated after all attempts. In patients without successful ETI (n = 31), supraglottic airways were used in 24, bag-valve mask ventilation in 5, and surgical cricothyroidotomy in 2, with an overall advanced airway success rate of 988/993 (99.5%). Conclusion: Critical care flight nurses and paramedics performed successful intubations in pediatric patients at a high rate of success. Younger age was associated with lower success rates. Improved ETI training for younger patients and use of an induction agent and NMB may improve airway management in critically ill children. [ABSTRACT FROM AUTHOR]

The article discusses a study that identified the impact of weather conditions on the incidence of dog bites. The study used data from a previous dataset that identifies demographic factors in pediatric dog bites in patients referred to the Children's Hospital of Pittsburgh in Pennsylvania. Dog bites were treated as a binary variable for statistical analysis. Dog bites were linked with warmer temperature and took place more frequently on days with rainfall.

Objective The objective was to determine the occurrence of, and the factors associated with, diastolic hypotension and troponin elevation or electrocardiogram ( ECG) ST-segment changes in a convenience sample of children with moderate to severe asthma receiving continuous albuterol nebulization. Methods This was a prospective, descriptive study in a pediatric emergency department and an intensive care unit of a tertiary academic center. Fifty children with moderate to severe asthma (clinical asthma score > 8) who received 10 to 15 mg/hour continuous albuterol for >2 hours between June 5, 2007, and February 4, 2008, were approached. Hourly diastolic blood pressures were recorded. Cardiac troponin I ( cTnI) and ECG tracings were obtained following the first 2 hours of albuterol and then subsequently every 12 hours while receiving continuous albuterol. Main outcome measures were: 1) incidence of diastolic hypotension, 2) incidence of troponin elevation, and 3) incidence of ECG ST-depression. Results Fifty patients were enrolled. Thirty-three (66%) patients developed diastolic hypotension during the first 6 hours of continuous albuterol. Diastolic blood pressure declined from baseline at 1-6 hours (p < 0.01 vs. baseline). Twelve patients (24%) had elevated cTnI, 15 patients (30%) had ST-segment change, four patients (8%) had both, and 23 patients (46%, 95% confidence interval [ CI] = 32 to 60) had either a cTnI elevation or an ECG ST-segment change. Troponin elevation and diastolic hypotension were not associated ( RR = 1.2, 95% CI = 0.6 to 2.3). Conclusions In a subset of children with moderate to severe asthma, diastolic hypotension, troponin elevation, and ECG ST-segment change occur during administration of continuous albuterol. Future studies are necessary to determine the clinical significance of these findings. [ABSTRACT FROM AUTHOR]

Objectives The emergency department ( ED) is characterized by stressors (e.g., fatigue, stress, time pressure, and complex decision-making) that can pose challenges to delivering high-quality, equitable care. Although it has been suggested that characteristics of the ED may exacerbate reliance on cognitive heuristics, no research has directly investigated whether stressors in the ED impact physician racial bias, a common heuristic. We seek to determine if physicians have different levels of implicit racial bias post- ED shift versus preshift and to examine associations between demographics and cognitive stressors with bias. Methods This repeated-measures study of resident physicians in a pediatric ED used electronic pre- and postshift assessments of implicit racial bias, demographics, and cognitive stressors. Implicit bias was measured using the Race Implicit Association Test ( IAT). Linear regression models compared differences in IAT scores pre- to postshift and determined associations between participant demographics and cognitive stressors with postshift IAT and pre- to postshift difference scores. Results Participants ( n = 91) displayed moderate prowhite/antiblack bias on preshift (mean ± SD = 0.50 ± 0.34, d = 1.48) and postshift (mean ± SD = 0.55 ± 0.39, d = 1.40) IAT scores. Overall, IAT scores did not differ preshift to postshift (mean increase = 0.05, 95% CI = -0.02 to 0.14, d = 0.13). Subanalyses revealed increased pre- to postshift bias among participants working when the ED was more overcrowded (mean increase = 0.09, 95% CI = 0.01 to 0.17, d = 0.24) and among those caring for >10 patients (mean increase = 0.17, 95% CI = 0.05 to 0.27, d = 0.47). Residents' demographics (including specialty), fatigue, busyness, stressfulness, and number of shifts were not associated with postshift IAT or difference scores. In multivariable models, ED overcrowding was associated with greater postshift bias (coefficient = 0.11 per 1 unit of NEDOCS score, SE = 0.05, 95% CI = 0.00 to 0.21). Conclusions While resident implicit bias remained stable overall preshift to postshift, cognitive stressors (overcrowding and patient load) were associated with increased implicit bias. Physicians in the ED should be aware of how cognitive stressors may exacerbate implicit racial bias. [ABSTRACT FROM AUTHOR]

BACKGROUND: Abusive head trauma is the leading cause of death from physical abuse. Misdiagnosis of abusive head trauma as well as other types of brain abnormalities in infants is common and contributes to increased morbidity and mortality. We previously derived the Pittsburgh Infant Brain Injury Score (PIBIS), a clinical prediction rule to assist physicians deciding which high-risk infants should undergo computed tomography of the head. METHODS: Well-appearing infants 30 to 364 days of age with temperature <38.3°C, no history of trauma, and a symptom associated with an increased risk of having a brain abnormality were eligible for enrollment in this prospective, multicenter clinical prediction rule validation. By using a predefined neuroimaging paradigm, subjects were classified as cases or controls. The sensitivity, specificity, and negative and positive predictive values of the rule for prediction of brain injury were calculated. RESULTS: A total of 1040 infants were enrolled: 214 cases and 826 controls. The 5-point PIBIS included abnormality on dermatologic examination (2 points), age ≥3.0 months (1 point), head circumference >85th percentile (1 point), and serum hemoglobin <11.2g/dL (1 point). At a score of 2, the sensitivity and specificity for abnormal neuroimaging was 93.3% (95% confidence interval 89.0%-96.3%) and 53% (95% confidence interval 49.3%-57.1%), respectively. CONCLUSIONS: Our data suggest that the PIBIS accurately identifies infants who would benefit from neuroimaging to evaluate for brain injury. An implementation analysis is needed before the PIBIS can be integrated into clinical practice. [ABSTRACT FROM AUTHOR]
